Wiki revisions disappeared!

I made revisions to my wiki yesterday that I saw and saved. When I look in my personal timeline, I see 8 revisions for Feb 8. However, when I go to the wiki, all of the revisions that I made yesterday are completely missing. The don't appear in the page histories, and the pages are in the state that they were in on Sunday. Pulling from the wiki repository shows no new revisions.

What the heck happened to my data?
